| FrancisANDRE | Hello Launchpad | 07:28 |
|---|---|---|
| FrancisANDRE | How can I get rid of this ERROR: ld.so: object 'libfakeroot-sysv.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored. | 07:28 |
| FrancisANDRE | when building on launchpad | 07:29 |
| cjwatson | mapreri: That's carried over from bzr and will eventually be implemented, but it doesn't mean much yet. | 08:15 |
| cjwatson | mapreri: I mean, some minimal git subscription mails are implemented, just not anything that's per-commit. | 08:18 |
| mapreri | cjwatson: oh, I see. Well, looking forward to it, then :) | 08:19 |
| cjwatson | FrancisANDRE: Hmm, that is a slightly unusual amount of noise. Let's see ... | 08:23 |
| cjwatson | FrancisANDRE: OK, I believe it's because your package (possibly the build/rules/global file) is setting LD_LIBRARY_PATH and discarding any previous value, rather than prepending/appending to it | 08:24 |
| FrancisANDRE | Ah ok. so appending the old LD_LIBRARY_PATH at this point should solve the noise? | 08:26 |
| FrancisANDRE | I will bive a try | 08:26 |
| cjwatson | Should do | 08:34 |
| stub | Would it be possible for a source package to install a snap as a build dependency? Or would Launchpad likely choke on that due to build environment restrictions? | 10:34 |
| cjwatson | At present it'd choke. It would require some thought. | 10:39 |
| cjwatson | It's not clear how it would work wrt chroots. | 10:41 |
| wgrant | Not to mention the technical questions, that would also totally destroy any kind of reproducibility. | 10:44 |
| cjwatson | It may be acceptable for builds of snaps themselves. | 10:46 |
| cjwatson | e.g. a snapcraft plugin that decided to install a snap | 10:46 |
| cjwatson | I think we talk to the store via the snap-proxy so it'd only be possible for snap builds anyway. | 10:47 |
| cjwatson | (I do wish snap builds did more pinning though.) | 10:47 |
| wgrant | Oh for snap builds maaaaaaybe, but not for source package builds. | 10:49 |
| stub | As an alternative approach, it might be possible to convert a .snap to a source package which builds to a binary package with the snap embedded and a install script that snap installs it | 11:02 |
| stub | goal here being to distribute software built with a snapped compiler via PPA | 11:03 |
| cjwatson | stub: The problem is that snap install is unlikely to work as it stands. | 11:05 |
| cjwatson | A binary package workaround doesn't help. | 11:05 |
| cjwatson | Snap builds can talk to the store (we did that for classic builds), but at present classic builds only need to be able to unpack the core snap to /snap/core/current/, not to actually have snap install working. | 11:06 |
| stub | At what point does it fail? The .snap should get passed through pristine to the point 'snap install' is run | 11:06 |
| cjwatson | snapd isn't running. | 11:06 |
| stub | The install would be run when the binary package is installed | 11:06 |
| cjwatson | Getting it running would require some acrobatics to make sure it's all shut down properly, etc. | 11:06 |
| stub | No snapd is needed when building the binary package | 11:07 |
| cjwatson | It sure is if you want snap install to work. | 11:07 |
| cjwatson | This binary package hack doesn't solve any existing problem on Launchpad builds. | 11:08 |
| cjwatson | So let's ignore it. | 11:08 |
| cjwatson | Well, I mean it might solve a PPA distribution problem, sure, that much would be OK. | 11:08 |
| stub | No, it is an alternative approach if we can't get builders to install snap dependencies | 11:08 |
| cjwatson | I think we're likely to need to solve that problem at some point. | 11:08 |
| stub | Ideally I'd like the equivalent in the snap store, and was just considering ugly hacks to avoid waiting. | 11:09 |
| cjwatson | But the PPA distribution approach still wouldn't allow those packages to be used as a build-dependency. | 11:09 |
| stub | Yes. And TBH we probably don't want to invest time in snaps as build-dependencies. | 11:10 |
| cjwatson | It would certainly be a ton of work. | 11:11 |
| cjwatson | I'd rather have the relationship be one-way, myself. | 11:11 |
| stub | +1 | 11:12 |
